First of all – Welcome 🙂
Well Traktor and Rekordbox are 2 very very different apporaches to DJing software.
Traktor relies much more on good preparation work (you need to have stem files and/or remix deck sets etc.) and in regard is lacking some “live control” features and is harder to beatgrid if you use something other than straight “boom boom” music.
However if you do DJ the boom boom genres (Techno, House, Electro,…) and have the preparation work, the level of creative freedom can be exceptionally good, especially if you combine stems and remix decks.
On the other hand Rekordbox (and also Serato) have a different approach. They basically tell you, do not do so much prep work, just get the usual singles with Full/instrumental/acapella versions and mix on the fly using “twitch” oriented features like slicer, instant sampler (Rekordbox) or Flip (Serato) or tone play (Serato). However these features in return take a lot more training as you are actually re-arranging a track on the fly live. So if you mess up everyone will notice (most likely), while in Traktor if you botch the prep-work you can re-do it. So prep-time wise both will be about the same, Traktor will be more time spending researching and using DAWs to cut in songs and Serato will more be simulating live play.
So you have to decide which workflow suits you best, there is no actual better or worse and I also have to say when I am attending gigs as a guest I can appreciate a good DJ no matter which form of workflow he does.
What I do recommend however is not to base you decision on the fact that with Rekordbox you “might” be able to use CDJs better. Doing that is bogus. You can use Traktor and download the free Rekordbox version any day. Creating a CDJ ready USB stick from rekordbox if you have pre-defined playlists is done in the same amount of time it takes you to prepare setlists and playlists in Traktor or any other software. It is easy as hell and very very intuitive. So if you ever come into that position just ask for more money. (If I have to use CDJs I ask for 30% more than my normal fee for the trouble of having to use outdated equipment. 30 seconds later any manager told me “bring what you want” and when they hear me perform in my gear, they never want anything else.)
